Actual behavior

Clicking on the 'Debug Test' link of a unit test method (not class!) results in all the unit tests of that class to execute.
Quick analysis:
The problem stems from the code change in #2066 on line 300, where a 'break' has been added in the first condition. Removing this makes the code work as before.

It also seems that the second condition (line 301) will never be reached due to this 'break'. This is because the first condition (line 298) is a more lenient check and will always be true when the second more stricter check is true. Unfortunately due to the 'break' the first condition will assign the whole class as the desired tests instead of the single test, which is assigned if he second condition is true.

Expected behavior

Only the selected unit test method should execute, as was the case earlier.

Steps to reproduce:

1. Create a unit test class (derived from unittest.TestCase)
2. Create a couple of unit test methods.
3. Assuming that the unit tests are discovered and the 'Run Test| Debug Test' links are visible, click on the Debug Test link of a method. --> All the Unit tests execute instead of only the desired test.
